Hi everyone, I am looking into changing my rear diff gear oil...what do you guys use? I have heard Lucas Oil or Amsoil are the ones to use, but anyone have experience using them? Or is something like Castrol good enough?

I use http://www.bosslubricants.com/products/gear-lubricants/BOSS FULL SYNTHETIC GEAR OILS SPECS.pdf but the first question is do you have a L/S? That will determine what you need and what you can use.
I don't have limited slip, but do have anti-spin. I asked the service dept. at the dealer and they said to still put the additive in for it.
i use redline synthetic. 75w140
